Ford Focus RS Performance Upgrades

Lethal Performance is a leader in the market for Ford Focus RS performance upgrades. Not only do we carry aftermarket parts for these cars, we use them too — on our own Focus RS that we bought specifically to test the products we carry for the 2016-2018 model. We've teamed up with our awesome vendors and manufacturers to see what parts they offer for this already-amazing vehicle from the Blue Oval. We like to start with an off-road downpipe, upgraded intercooler, cold air intake and custom tuning from Lund Racing. However, if you're like us, there's a good chance you'll want to take it a step further with an aftermarket turbo kit and auxiliary fuel systems. So, if a turbocharged 345 hp 2.3L EcoBoost from the factory just isn't enough, get Ford Focus RS performance upgrades from Lethal today!
